This invention "relates to machines" for straightening 'clutchdisks and similar ar-- tides: and is illustrated as embodied in a modification of astandard drill press. Prefa erably the disks are straightened byrrolling them in such a manner as to flex various portions of the disk back and forth, to straighten out any Warped or bent parts.

In one desirable arrangement,lthere are or freely-rotatable, sets two novel floating, or units of rollers, engaging respeotlvely. the upper andlower surfaces of the clutch'disk, the rollers of one=setpreferably being staggered with respect to thoseof the other set,

to secure the described flexing action. .In order to provide for readily inserting-andwithdrawing the disks, the parts on the opposite sides of the disk-may be arrang be separated axially of the disk, and in the arrangement illustrated in the drawings these parts are arranged in a' novel manner such {that they are automatically brought into operative inter-engagementby their re-- turn to the workingposition." I find-it advantageous'in practice to use conical rollers upper and lower conical "tracks,

supported by g so that a very heavy pressure may be exerted on the diskswithout any binding of the moving parts. i The above and other objects and features of the invention, including various novel combinations of parts and desirable particular constructions, Will be apparent from'the following description of" one illustrative embodiment shown inqthe accompanying drawings, in which 2; i 9

series of conical trollers=30 engaging its lower: surface, the rollers being supported by rolling on a conicaltrack 32 secured by machine'screws'34 to a plate 36 carried'by the base 10. Each roller is journaled on a spindle 38 projecting inwardly from a ring 40, a thrust bearing 42 preferablybeingprovided. at the base'of the roller: Rotatably mounted ona thrust bearing 44 on track 32 1s a bed 46, having fingers 48 entering-"the usual notches in the edge of disk D.
